�烷基化脱氢塔分离不好??????
Reply #42017-07-31
公司脱氢塔四段填料塔最近分离不好,顶上带C4下面带C3,现在塔压14公斤,塔顶冷后温度44度,以前正常时塔底气相返塔温度与第四段填料温度差只有2、3度现在7度多。塔底提温底温没涨顶温直涨,总是感觉塔的内部有问题。C3在控制不好估计要停了!!!!!

是啊,塔底控制不住C3,烷基化反应没法干了。从以下几个方面入手查找哦: 1、原料中的C3组分高,或是有其他的轻组分。建议做下二氧化碳和氮气的化验。 2、冷却水温度高,回流液体温度高。 3、塔盘长时间使用有所腐蚀,建议更换塔盘。

五月份停车之前也是这情况,后来停车检修,塔也就是退料蒸了一下,领导跑上去看看讲填料没事,这不6月份开车之前量小还好现在量大了又出老毛病了。之前停车退料时在碳3原料泵注水退料最后水有很多进了回流罐到塔底很少
